Treponema pallidum hemagglutination assay

Treponema pallidum hemagglutination assay
(TPHA) a serologic test for syphilis that measures specific treponemal antibodies. It combines nonhuman red blood cells sensitized with antigen from a strain of Treponema pallidum with patient serum absorbed with an extract of other treponemes for removal of nonspecific antibodies; hemagglutination denotes a positive result.
